Query 20160519_223238_81890_gf734 failed: TOO_MANY_REQUESTS_FAILED: Failed to read f1a04ceb-c217-4ee4-ba4f-17b10c78ec9f.
The TOO_MANY_REQUESTS_FAILED error indicates that there are many data reading errors. Presto itself does not have fault tolerance, so in this situation, it will exit with an error once. By re-executing the query in TD, the query itself will be successful. Therefore, the log will be cleared once, but the Presto query will be re-executed after a few minutes.
The message happens when our internal error increased. But, presto job retries automatically, so the job succeeded.
Presto job retries automatically or re-execute the query in TD.
